http://androidforums.com – Hi everyone, I have a galaxy s3. I forgot my screen lock password, and the problem is, I DONT GET THE "FORGOT PASSWORD" option where you enter your gmail info to bypass. How do I get that option? I suspect this might be because my gmail was not properly synced to my phone...? Provider says they can't help. PLZ PLZ help. my only concern is saving data, and that's why i won't reset my phone yet. (General)
